SMOKE, SPARK, AND CINDER ARRESTER.

SPECIFICATION forming part of Letters Patent No. 396,697, dated January22, 1889.

Application filed August 2'7, 1888- Serial No. 283,830. (No model.)

T [6 whom, it may concern:

Be it known that I, WALTER B. JoHNsoN, a citizen of the United States,residing at Fredericktown, in the county of Knox and State of Ohio, haveinvented certain new and useful lmprox'ements in Smoke, Spark, andCinder Arrest-ers; and I do hereby declare the follow ing to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in a device for arresting thesparks, smoke, and cinders in the smoke-stack of a railroad-engine andconveying the sparks and cinders back to the tender and the smoke to therear end of the hindmost car.

The object of my improvements is to provide a means of preventing two ofthe most disagreeable lt'catu res or objections known to railroadtravelingfirst, that of the smoke escaping from the smoke-stack ofengines and entering cars impregnated with the most offensiveot' odors;second, that of arresting the cinders and sparks in the smoke-stack andconveying the same back to the rear of the tender, where they are dumpedin a box placed there for said purpose, thereby preventing the sparksfrom igniting with dry material along the railroad, sometimes cansin ggreat loss, or the cinders from entering the car, creating dust thatsettles upon and disfignres clothing, rendering them worthless, as wellas getting in the eyes of passengers, inf'lictin g serious injury. Iattain these objects by the combination and arrangement of parts fullydescribed in the specification and illustrated in the micom ntnyingdrawings, in which Figure l is a view of my device attached to thesmokestack and cars and in a position for use. Figs. 3 and are sectionalviews showing the means of connecting the ends of pipe between the cars.Fig. is a longitudinal sectional view through the center of section 0.Fig. 5 is a similar view of the section D. Fig. 6 is a transverse viewof the section D on the line a: :r. Fig. 7 is a view of the damper orshutoff located in the smoke-stack at the point the device interceptsthe same.

Figs. 8 and 9 are transverse views of the smoke-stack at the point wherethe damper is located, showing, respectively, the position of the damperwhen closed and when open. Fig. 10 is a "iew of the damper and means ofoperating same detached from the smokestack.

The device is composed. of the sections A, B, (l, and D. The section Aintercepts the smoke-stack E at the point shown in Fig. 1. At this pointthere is an. orifice, a, in the smokestack leading into a similar fineor orifice, a, in the section A,thence continuin g backward through thedifferent sections to the rear end of the hindmmt car.

The damper F is located at the upper edge of the interception of thesmoke-stack E and the section A. Said damper corresponds in shape to theflue of the smoke-stack, which is usually circular, in order toeii'ectually close said flue at the point named.

The damper F is secured to the rod G,which has bearings g at thejuncture of the smokestack E and the section A. This damper is operatedfrom the cab of the engine by means of the rod G. It will be readilyseen that by drawing backward the rod G the flue of the smoke-stack isclosed, as shown in Fig. 8, and by pushing said rod forward it isopened. This will enable the engine to be used. with or without mydevice, accordingly as it is desired. \Vhen the rod G is detached at thepoint g, the damper assumes the position shown in Fig. 9. A portion ofsection A may then be detached at the elbow a, and the en gine can thenbe used. to draw freight or for any purpose required without my device.

The section A is made with the elbow a in order to extend the continuouspipe (composed of the aforesaid different sections) to a sufficientheight to clear the top of the cars.

H designates the elastic leather or strong canvas used between the cars,which is con structed with a view of detaching the cars at any point andof permitting them to adaptthemselves freely to the irregularity oftrack. The pipe is formed at said place with a raised ring, ed, as shownin Fig. 2. The elastic H has located in. its ends the spirally-coiledring h, as shown in Fig. 3.

It will readily be perceived that when it is wished to separate the carsall that is necessary is to uncouple same, and the elastic when pulledwill expand and slip off of the pipe. \Vhen the cars are again coupled,the elastic, in combination with the spirally-coiled elastic band, canbe expanded and again slipped over the raised ring (6 so that it is onlynecessary to have a brakeman couple or unite my device when the cars arecoupled, but not when uncoupled. In the latter event it isself-operative.

The section 0 is constructed with a larger pipe, G, surrounding it, asshown in Fig. at. Said pipe is secured and supported by the braces c.The purpose of the pipe 0 is to create a powerful draft to force rapidlyand effectually the smoke and cinders through the pipe. It is evidentthat as the large pipe 0 is open in frontit will always catch a strongdraft, which is generated by the motion of the cars. Said draft isstrong in proportion to the speed of the cars, and at all times does itswork thoroughly.

The section D is formed as shown in Figs. 5 and 6, repeetively. Theperforated screens (Z catch the cinders, which drop into the orifices d,and are conveyed thence into the rear end of tender, while the smoke isdriven out the rear end of the pipe at the end of the hindmost car, andis thereby gotten rid of effectually.

As my invention is very simple in construction and effectual inoperation, it is useless to further enlarge upon its merits.

I attach importance to the construction and arrangement of the sectionC. The larger pipe, 0, surrounding it creates a uniform draft at allpoints in the pipe, thereby making a clean sweep of the cinders. If thedraft were admitted at the top by hoods or proj ectin g caps atintervals along the sections, as has been done in inventions of thiskind, it would not be as strong and uniform in the pipe. Besides, wherethus admitted a heap of cinders always collects in front of the cap orhood, owing to the forward pressure of the air in entering the pipe. Myimprovement in constructing the larger pipe, 0', to completely environthe smaller pipe obviates this difiiculty. I also attach specialimportance to the perforated screens (1, located in section D, and tothe downwardly-projeeting portion of said sect-ion, by means of whichthe cinders are separated from the smoke at the rear of the tender, intowhich they are dropped. Thisis one of the main features of my invention,because I am aware that cinder and smoke eonductors have heretofore beenconstructed with a pipe extending the full length of the train; butafter a thorough trial of same they have proven to be impracticable,simply because of the fact that the cinders could not be forced throughthe entire length of the pipe upon a very long train. It has beendemonstrated that the cinders will collect in heaps in being transmittedthrough a long pipe, and if not constantly watched the pipe will soon.become filled and do incalculable harm. For this reason the screens (Zand the downwardly projecting portion under said screens are decidedimprovements, as they entirely remove the difficulties aforementioned.

hat I claim is- The smoke and cinder conductordescribed, consisting ofthe section A, the shut-off located at the junction of said section andthe smoke-stack, the section 0, having the larger pipe, 0, surroundingit, the section I), having the perforated screens (1 and thedownwardly-projecting flaring portion under said screen, and providedwith the orifice d, the flexible couplings H, and the section 15, allsubstantially as described and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

XVALTER B. JOHNSON.
